How we handle new build mastic in Carberry
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. Common call-outs are for second-fix sealing on new plots and cracks appearing as a new home settles, on bathrooms & en suites, skirting & floors and show homes.
New homes in smaller Scottish places are often single plots, self-builds or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Is Carberry within the area you cover?

Should I go to my builder first?

Can you do plot mastic on a new development?
Yes. We take on second-fix sealant work across new plots. We clean and prime joints properly to keep callbacks down.
Do you work for hotels and businesses?

Aftercare tips
After the cure time, these simple habits help:
- Get a leaking seal dealt with straight away
- Watch for new gaps as the house dries out
- Keep photos and emails about snagging items
- Resist patching a failed seal with a tube from the DIY shop
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak in a busy bathroom.
Joints and finishes in Carberry homes
Carberry is within about 3 miles of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
If you’ve bought a new home near Wallyford station, the sealant around baths, showers and frames is worth checking in the first year or two.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

To help us quote quickly, let us know:
- Photos by email, if that’s easy

Common problems we fix in Carberry
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used.
Any of these means the joints need attention:
- Worktop and upstand sealant coming away
- Internal frame sealant that has split
- Untidy sealant flagged on a snagging list
- Plot mastic for developers ahead of handover
Around Carberry, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before you book
- Is the old sealant removed completely?
- What happens if the job turns out different
- What the quote includes, VAT included or not
- What product goes in the joint
